Adjustment layers are one of the most powerful tools in Photoshop, and they can be used for a variety of tasks. In this article, we will explore the different types of adjustment layers and how many you can have in Photoshop. First, let’s take a look at what an adjustment layer is. An adjustment layer is a type of layer that allows you to modify the appearance of an image without affecting the underlying document. This means that you can add or remove colors, brightness levels, and other adjustments without affecting the underlying document structure or content. There are three main types of adjustment layers: color, brightness, and contrast. Each type has its own set of properties that you can adjust to achieve different results. For example, you can adjust the color intensity or hue to change the overall color tone of an image. You can also adjust the brightness level to make an image more or less visible onscreen. And lastly, you can adjust the contrast level to create a more dramatic effect. Now that we know what an adjustment layer is and what its main properties are, let’s take a look at how many adjustment layers you can have in Photoshop. By default, Photoshop allows you to have up to 10 color adjustment layers and 10 brightness/contrast adjustment layers per document. However, there are some exceptions to this rule – for example, if you want to use a masking tool (like the Brush Tool) with an adjustment layer active, then Photoshop limits your total number of active masks to 1 per layer (not including background masks). So keep this in mind if you plan on using lots of masks with your adjustments! ..
